HARRY D. BARTLETT AND WILLIAM F. J. LUTZ, OF CHICAGO, ILLINOIS.

WATER-CLOSET BEND.

T 0 all whom it may concern:

Be it known that we, HARRY D. BARTLETT and WILLIAM F. J. LUTZ, citizensof the United States of America, and residents of Chicago, county ofCook, State of Illinois,

have invented certain new and useful Improvements in lVater-ClosetBends, of which the following is a specification.

The main objects of this invention are to provide an improved form ofwater closet bend, provided with an adjustable flange adapted to bereadily raised and lowered to suit varying conditions; and to provide adevice of this kind which avoids the necessity of outside calking andwhich may be readily adjusted through the inside of the flange.

An illustrative embodiment of this invention is shown in theaccompanying drawings, in which:

Figure l is a side elevation partly broken away of a closet bendconstructed according to this invention. Fig. 2 is a longitudinalsection of the same. Figs. 3, 4 and 5 indicate successive steps in theassembling of the joint.

In the construction shown, the main body 1 of the bend is of usualconstruction, but is provided with an internally threaded hub 2, saidhub being of larger diameter than the body part, and there is an annularshoulder providing a seat 3 for a. gasket or packing ring 4:. A nipple5, threaded on its exterior to fit the hub 2 and also threaded on itsinterior, forms an adjustable extension of the bend and carries on itsupper end a flange 6 adapted for attachment to the closet bowl. An innerpart or ring 7, having its interior diameter substantially equal to theinterior diameter of the body 1, is threaded on its outer periphery tofit the inner threads of the nipple 5. The ring 7 is preferably ofsubstantially the same length as the hub 2, and is notched at 8 toprovide shoulders for engaging with a spanner by means of which the ring7 may be turned and forced into liquid-tight and gas-tight engagementwith the gasket 4, which gasket is preferably formed of copper or othersoft metal. In addition to forming a tight joint at the gasket, thepressure of the ring 7 upon the shoulder 3 causes the inside and outsidethreads of the nipple 5 to be clamped by the threads on the hub 2 andthe ring 7 in such manner as to form a liquidand gas-tight jointthroughout. The nipple 5 is thus con- Specification of Letters Patent.

fined between inside and outside walls and has a tight joint with both.

In assembling the device, the bend 1 is first placed in position, itselevation being determined as near as can be roughly estimated, beforethe floors of the building are laid. The adjustment of the flangepermits the same to be brought to the exact floor level after the flooris in position, and as the inside is then more easily accessible thanthe outside, the advantage of being able to make the oint tight by anadjustment from the inside is obvious. On inserting the parts into thehub of the bend, the ring 7 is first screwed into the nipple5 as in Fig.3, and the nipple 5 is then screwed into position in the hub 2. Afterthe flange 6 has been adjusted to the proper elevation, the ring 7 isscrewed home until it has a suflicient bearing upon the gasket 4 toinsure that the joint throughout will be gas and water-tight.

Although but one specific embodiment of this invention is herein shownand described, it will be understood that some of the details of theconstruction shown may be altered or omitted, within the scope of thefollowing claims, without departing from the spirit of this invention.

We claim:

1. A device of the class described, comprising a bend having a hub atone end, a nipple extending into the hub and having adjustableconnection therewith, an inner part located concentrically within thenipple and being substantially co-extensive with said hub, and means forproducing a gas tight joint between said nipple and said hub and innerpart.

2. A device of the class described, comprising a bend having a hub atone end, a nipple extending into the hub and having an integraloutwardly extending flange at its upper end, an inner part locatedconcentrically within that part of the nipple which is surrounded by thehub, and adjustable longitudinally of said nipple, and means forproducing a gas tight joint between said hub and inner part.

8. A water closet bend having an internally threaded hub and having aninwardly extending annular shoulder located inward of the threads onsaid hub, a flanged nipple having threaded engagement with said hub, aring telescoping with said nipple and adjustable toward and away fromsaid Patented Jan. 3, 1911..

shoulder, and shoulders on said ring whereby it may be adjusted from theinside of said nipple.

4. In a device of the class described, the combination of a hub havingan inwardly extending shoulder on its under end, a nipple havingthreaded engagement with said hub, and a ring having threaded engagementwith said nipple and adapted to bear on said shoulder so as to exert anendwise thrust on said nipple, to jam said threads and produce agastight joint.

A water closet bend having an upwardly disposed hub internally threadedand having an annular shoulder below the threads thereon, a nippleflanged at its upper end and having threaded engagement with said huband a ring having threaded engagement with said nipple and adjustabletoward and away from said shoulder independently of the adjustment ofsaid nipple within said hub.

(3. A water closet bend having an upwardly disposed hub internallythreaded and havin an annular shoulder below the threat s thereon, anipple flanged at its upper end and having threaded engagement with saidhub, a ring having threaded engagement with said nipple and adjustabletoward and away from said shoulder independently of the adjustment ofsaid nipple within said hub, and a gasket interposed between said ringand shoulder.

7. A water closet bend having a hub at its upper end and an annularshoulder extending inwardly below the threads in said hub, a nipplehaving threaded engagement with said hub and. being internally threaded,an externally threaded ring telescoping with said nipple and adjustabletoward and away from said shoulder for insuring a gas and water-tightjoint regardless of the position of said nipple in said hub.
